The Lancet: Patients with complications after major surgery more likely to survive if readmitted to the same hospital
Patients rehospitalized with complications after major surgery are 26 percent more likely to survive if they return to the hospital where they had their operation compared to those readmitted to a different hospital, according to a national study involving over 9 million Medicare patients in the USA, published in The Lancet.

Conflicting histories harm negotiations, researchers say
New research published in the Journal of Economic Behavior and Organization examines how past histories are harmful in negotiations, particularly when an event in the past benefited one party at the other's expense. In those situations, the party that got the short end of the stick tends to believe that they are owed retribution. The party that triumphed in the past, in contrast, tends to think that the past is irrelevant -- bygones should be treated as bygones. (2015-06-17)

Ultrasound identifies RA patients in clinical remission who need more intensive treatment

New treatment approach to limit damage after joint bleed
The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) identified that the cytokine Interleukin-1β (IL-1β) is a crucial factor in the development of blood-induced cartilage damage. This finding opens up the possibility that a treatment targeting IL-1β could provide a new way to protect cartilage after a joint bleed, which in turn should significantly reduce subsequent disability.

University of Iowa team developing bioactive gel to treat knee injuries
Current surgical options for repairing damaged cartilage caused by knee injuries are costly, can have complications, and often are not very effective in the long run. But a University of Iowa orthopedics research team is working on a biologic solution -- an injectable gel that encourages self-healing of cartilage -- with hopes it will result in a minimally invasive, practical, and inexpensive approach for repairing cartilage and preventing osteoarthritis.

Age at surgery and valve type in PVR key determinants of re-intervention in congenital heart disease
Survival of children with congenital heart disease has greatly improved, so that currently there are more adults than children living with CHD. Consequently, people with CHD of all ages are undergoing pulmonary valve replacement with bioprosthetic valves. In this retrospective review of all patients with CHD who underwent bioprosthetic PVR over an 18-year period at Boston Children's Hospital, investigators found that young age, small body weight, type of valve used predisposed patients toward re-intervention.

Most women don't know female-specific stroke signs
A new national survey shows that most women don't know the risks or symptoms females face when it comes to having a stroke. The survey, released by The Ohio State University Wexner Medical Center, found that only 11 percent of women could identify female-specific risk factors for stroke from a list and nine out of 10 weren't aware that hiccups combined with chest pain are among the early warning signs of a stroke in women.

Patient's own fat cells transplanted to treat osteoarthritis may be effective
Studying the effectiveness of using osteoarthritis patients' own adipose cells for transplant therapy aimed at reducing OA symptoms, researchers recruited 1,114 OA patients who received autologous fat cell transplants. Evaluation demonstrated that at least a 75 percent improvement was noticed in 63 percent of the patients and at least a 50 percent improvement was documented in 91 percent of the patients after 12 months. Results also showed that painkiller usage declined dramatically after treatment. (2015-04-16)
